i o all 'whom 'it may concern.

it knownthat we., @Vitamin HENRY Noswon'rii and SAMUEL' nains Pnnsoorr,

subjects of His Majesty the lging oit England, .residing at London, England, have invented certain new and useful lmprovements 'in 'Hydroaeroplanesg of which the following is a speciication.

This invention relates to hydro-aeroplanes and is directed to securing promoting lateral steadiness of such machines when waterborne.

By and in accordance with thelpresent invention provision is made to edectively damp rolling action of the machine when traveling, or riding at anchor, on lthe water, and to this end water buckets or their equivalents are adapted to be suspended one from each side of the supporting plane or planes and adjacent to the extremities thereof; these water buckets or their equivalents being formed of a material giving a power or tendency to float in the water, an appro priate material being oak which has a speciic gravity slightly less than water. ln smooth water the buckets or equivalent on each side of the machine would be submerged in the water, but under a lateral rolling motion of the machine they would be alternately lifted and submerged, this alternate lifting oi' the buckets on either side, eilectively dampening the rolling motion of the hydro-aeroplane, in virtue of the opposing force of the weight of water contained in the buckets. Means for releasing the water contained in said vessels, such as a valve arranged for release when the buckets are to be put out of use, or perforations, may be made in the said vessels whereby the water may enter and drain away gradually, or the expedient of tilting the buckets may be adopted. Provision for withdrawing and storing the buckets will be made in appropriate manner; for eXample, rope gear may be provided whereby the water-vessels may be pulled up to the under-side of the plane or planes of the machine, or hauled into the ioats or chassis when said vessels are not in use. yllhe water vessels may be collapsible so that they will occupy less space when stowed away, and in, this construction special Specification of Letters Patent.

Sept. Serial No. 2547,53?.

invention each bucket consists of a disk iioat i a having an aperture o therein7 and to this float is suspended self-entendible waterproof bellows or casing c, the automatic eX- tension of the bellows bei conveniently and advantageously derivan spiral spring Z which is of' tapered forni so that the coils thereof may tit one within the other when the bellows or casing c is collapsed thus allowing the said casing` to occupy a very small space. bucket is formed by an apertured plate e of relatively high specific gravity and 'litted on the upper side with a non-return disk valve f whereby on the lowering of the bucket into the water, water may enter the bucket by way of the apertured base c but any substantial return of the water is prevented by the disk f Aacting as a non-return valve. Guidance for the disk valve f is furnishcd as depicted by a stem g fastened to the base c and having provision such as by means of an eye L for connecting the bucket to rope gear whereby the buckets may be withdrawn from the water and. collapsed against the underside of the supporting planes of the machine or hauled inte the Heats of the chassis of the machine. The rope gear will have suitable provision for locking it in the desired position.

The drawings illustrate conventionally a rope winding gear c for pulling the il ts in a collapsible state against the underside of the supporting plane y' see Fig. 3.

lnoperation the aperture of the iioat a admits oi a rapid release oit the water in. the act of collapsing the buckets but if desired the release of the contents may i'aci'f itat/ed in virtue of The base et the T ice by side apertures in addition or in substitution to the aperture t.

rlhe buckets will be adjusted or suited to the specific gravity ot the Water so that they oat therein when fully submerged. By making the top of the bucket of relatively low specic gravity and the base of rela-- tively high specilic gravity a rapid immersion of the bucket or the like in the Water is gained.

In operation any lateral tilting of the machine is at once opposed by the weight of a Water lilled bucket on the rising side of the machine, and the result would be that the machine Would slide sidevvise in 'the Water and recover its horizontal position, Whereas With the present system of employing floats on each side of' the main hydroaeroplane oat there is nothing to resist the tilting ,motion until the side float on the descending side of the machine becomes Water-borne and by the time this occurs the machine is heeled over to such an extent that a gust of Wind or a Wave striking the underside of the planes is liable to complete the heeling movement and turn the machine completely over, but in accordance With the present invention the submerged Water filled bucket on the descending side of the machine is inactive for the time being and an eftective resistance is realized on the ascending side of the machine.

I-Iaving thus described the nature of our said invention what We claim and desire to secure by Letters Patent is l.
